We evaluate the renormalization factors of the domain-wall fermion system with various improved gauge actions at the one-loop level. The renormalization factors are calculated for the quark wave function, quark mass, bilinear quark operators, and three- and four-quark operators in the modified minimal subtraction [Formula Presented] scheme with dimensional reduction as well as with the naive dimensional regularization. We also present detailed results in mean field improved perturbation theory. © 2003 The American Physical Society.
